Voalavo gymnocaudus, also known as the Northern Voalavo,Naked-tailed Voalavo, or just Voalavo, is a rodent in the family Nesomyidae found in the highlands of northern Madagascar. Discovered in 1994 and formally described in 1998, it is the type species of genus Voalavo; its closest relative is Voalavo antsahabensis of the Central Highlands. DNA sequence data suggests it may be more closely related to Eliurus grandidieri than to other species of the closely related genus Eliurus. V. gymnocaudus is found at 1250 to 1950 m (4100 to 6400 ft) above sea level in montane wet and dry forest in the Marojejy and Anjanaharibe-Sud massifs. Nocturnal and solitary, it lives mainly on the ground, but can climb, and probably eats plant matter. Despite a small range, it is classified as "Least Concern" because it lacks obvious threats and much of its range is within protected areas.
